Here is a C#.net application which displays the exact values of any range of samples of wave files:
http://www.jensign.com/showsamples
Supported wave formats: pcm (uncompressed) stereo 16bit/24 bit any sampling frequency
with standard RIFF wave header.
The wave header is parsed for validity. Then all information about the wave is shown.
The SHA-1 hash value of the data chunk is then shown (which enables bit-accurate checking
if sample data has been modified).
The user selectes a range of samples to display.
The wave values are listed in either decimal, hexadecimal or hexadecimal little-endian order.
The min/max sample values of L/R channels are displayed.
24 bit sample values are displayed exactly.
